“…This study uses NBI for developing regression models for bridge condition prediction. It should be noted that because the deck of bridge deteriorates more rapidly than the superstructure and substructure (Bolukbasi et al 2004;Hatami et al 2012), prediction models were developed only for bridge decks.…”

“…Predicting bridge condition with respect to its age using the NBI has been studied extensively in the past decade (Li et al 2010;Tabatabai et al 2010;Hatami et al 2012). However, because the NBI does not include any information about the applied load, deterministic approaches (e.g., finite element analysis) are preferred for quantifying the overweight load effects on bridges (Chotickai et al 2006;Dey et al 2014).…”

Permits are one of the most effective and common tools for state agencies to regulate the operation of overweight and oversize vehicles by ensuring the safety of passenger and freight traffic and minimizing damage to pavements and bridges while promoting commerce and the safe movement of goods and services. Although the State of Illinois uses a relatively comprehensive permit system, many of its parts have not been revised for more than 30 years. Therefore, the objective of this study was to revise the current permit system by evaluating up-to-date impacts of overweight vehicles. In this study, impacts of overweight (OW) vehicles were evaluated in three aspects (bridge, pavement, and traffic safety) and individual fees were developed for each. The most recent databases on infrastructure condition and state-of-the-art prediction/classification algorithms were employed to produce the realistic and up-to-date assessment of OW vehicles' impact. Finally, a combined permit fee was recommended as a function of miles to be traveled, as well as axle and weight information, by aggregating the calculated individual fees. 17.

Partridge. We also thank Mr. Jeremy Hunter, who provided information about INDOT's bridge maintenance program and shared his vision for INDOT's NDT program. Finally, we sincerely appreciate the valuable contributions of the consultants, manufacturers, and vendors who shared their vast knowledge and experience in NDT testing. JOINT TRANSPORTATION RESEARCH PROGRAMThe Joint Transportation Research Program serves as a vehicle for INDOT collaboration with higher education institutions and industry in Indiana to facilitate innovation that results in continuous improvement in the planning, design, construction, operation, management and economic efficiency of the Indiana transportation infrastructure. Type of Report and Period CoveredFinal Report Sponsoring Agency Code Supplementary NotesPrepared in cooperation with the Indiana Department of Transportation and Federal Highway Administration. AbstractThe deck is among the most expensive components of a bridge over its lifetime because of the frequent and costly maintenance and rehabilitation required. Currently, the Indiana Department of Transportation (INDOT) performs visual inspections of a bridge deck as the principal means of determining its condition, which enables the inspector to definitively document the surface condition while the unseen condition below the deck surface is left to the inspector's expert judgement. To compensate for this lack of data, INDOT supplements visual inspections with programmatic scheduling for major work actions, which is very effective for INDOT but costly. In this continuing era of funding shortfalls, INDOT commissioned this study to investigate nondestructive testing (NDT) methods to fill their data gap to inform its work action decision. The NDT methods have been shown to accurately locate corrosion and delamination and are a cost-effective alternative. A project level comparison between the NDT methods was performed to show which method, as well as which combination of methods, were the best choices from a cost perspective. A project level analysis of 30 bridge decks was performed, and those costs were compared to the costs of the current INDOT programmatic schedules. Finally, the analysis was expanded to the network level, which included the entire bridge inventory in Indiana. The results of this study indicate that implementing the NDT methods is cost-effective for INDOT at both the project and network levels.

Sustainability and resilience are important properties of transportation infrastructure. Considering the connection and interaction between them, this paper provides an integrated method for quantitative assessment on resilience and sustainability of transportation infrastructure. In view of the complex, multidisciplinary nature of the problem, this paper breaks the process into three logical modules that can be studied and resolved in a rigorous and consistent manner. By employing time-dependent reliability and the time-dependent probability of exceeding a damage state as parameters, a robust multi-objective maintenance decision-making method simultaneously considering effects of probable extreme events and natural deterioration is provided. By introducing the 3-D resilience model and six-parameter sinusoidal-based recovery model in resilience theory, the result of risk assessment which involves much inherent uncertainty turns to be more reasonable. Finally, advancing quantification methods of sustainability and resilience are proposed to accomplish the comprehensive assessment with a case study. The method can be used to guide informed decision making in transportation asset management, promote the construction of resilient transportation infrastructure, and accelerate the sustainable development of the city.
